activeavoidance response (aar) decreased obviously, and active avoidance response latency (aarl) and escape response latency (erl) were significantly prolonged after wbbi.
at pre-operation and 2, 4, 8 weeks after 4-vessel occlusion, the cognitive function were observed by computerized shuttle-training case and expressed by the ratios of active avoidance response (aar).
于造模前,造模后2,4,8周进行穿梭箱检查,以主动回避反应比率表示大鼠的认知能力。
methods the methods of multiple training active avoidance response that include step-down test, step-through test and water maze for mice were used to observe the effect on learning and memory.
